10 Claims.

This invention relates to improvements in cellular cartons.

The main objects of this invention are:

First, to provide a cellular carton or box which may be formed of a single blank with a minimum of stock and waste or scrap and one in which the parts are so associated that the carton may be quickly set up or erected and one which when set up is quite rigid even when formed of relatively light stock. a

Second, to provide a box or carton well adapted for the effective display of merchandise disposed therein and at the same time, one in which the merchandise is eifectively enclosed and protected.-

Third, to provide a carton or box having these advantages which is attractive in appearance when erected and with the merchandise or contents arranged therein.

- Further objects relating to details and economies of the invention will appear from the description to follow. The invention is defined in the claims. v

An embodiment of the invention is illustrated in the accompanying drawings in which:

Fig. 1 is a perspective view of a carton embodying my invention fully set up. I

Fig. 2 is an enlarged transverse section on a line corresponding to line 22 of Fig. 1.

Fig. 3 is a top perspective view of the carton partially erected.

Fig. 4 is a fragmentary perspective view partially in longitudinal section.

Fig. 5 is a view in longitudinal section illustrating steps in the erecting of the carton, one end wall being illustrated in partially erected position by full lines and erected position by dotted lines.

- Fig. 6 is a plan view of the blank.

The embodiment of my invention illustrated is formed of a single blank and comprises a bottom designated generally by the numeral I made up of bottom members or sections 2 and 3; The side walls 4 are'hingedly joined to the inner edges of the bottom members as they lie in the blank by the hinging scores 5, the hinging scores 5 being at the bottoms of the side walls andiouter edges of the bottom members when the carton is erected. The end walls 6 are disposed within the inner edges of the side walls as viewed in the blank and separated from their inner edges by the slits I. The ends of the end walls and the ends of the side walls are connected by the corner members 8 which are hingedly secured to the end walls at 8 and to the side walls at l0 and have diagonal folding scores H and slits l2, aligning therewith. These corner members are folded on the inner sides of the end walls when the carton is erected as is most clearly shown in Fig. 4.

The end walls have tucking flaps l3 at their bottom edges, these being joined thereto by the hinging scores I 4, these being slits IE5 at the ends of these hinging scores. These slits form locking tongues I6 adapted to engage with the locking lugs I! when the tucking flaps are tucked under the infolded corner members as is clearly shown in Fig. 4. The endwalls 6 are desirably of a width substantially exceeding the width of the side walls so that the end walls when erected extend substantially above the side walls to provide wrapper supports and to expose the contents at the sides of the carton. The end walls have inturned wrapper supporting flaps l8 joined thereto by the hinging scores IS. The bottom wall member 2 is at one end of the blank, a longitudinal partition member 19 being at the other end of the blank and hingedly joined to the bottom member 3 by the hinging scores 20. The bottom members 2 and 3 are overlapped and adhesively secured with the member 3 uppermost, the longitudinal partition member lying on the bottom when the carton is collapsed but being hingedly secured thereto so that it may be swung to an upright position when the carton is erected.

The blank is scoredand slit to provide transverse partition members, there being three of them 2|, 22 and 23, in the structure illustrated. The transverse partitions are hingedly connected to the upper edges of the side walls by the hinge members 24 which are hingedly connected to the side walls at 25, the partition members being hingedly connected to the hinge members at 25. It will be noted that the transverse partitions 22 and 23 are arranged to be swung oppositely in erecting and collapsing the same and they are out on their lower edges to provide tongues 21, 28 and'29. It will be understood that the number of tongues would be varied according to the width of the carton, the tongues providing transverse partition members which extend to the bottom of the carton. When the transverse partition members 22 and 23 are erected the inner edges of their tongues 2'! supportingly engage opposite sides of the longitudinal partition. The transverse partition 2| has a slit 30 extending from its bottom edge, this slit being adapted to receive the longitudinal partition and the edges of the slit closely embracing the longitudinal-partition and providing an effective lateral support therefor.

The longitudinal partition is provided with notches 31' in its upper edge adapted to receive the transverse partitions, these notches being conformed to provide stops 32 to limit the swing of the transverse partition to an upright position. The longitudinal partition is notched at 33 to receive the tucking flaps l8. In the embodiment illustrated, the upper edges 34 of the transverse partitions are substantially in the plane of the wrapper supporting flaps l3 of the end walls so that they coact therewith in supporting a wrapper as shown at 35 in Fig. 2.

With this arrangement of parts I provide a double row cell carton, the contents of both rows of cells being effectivel displayed through the transparent wrapper and at the same time effectively protected. The carton when erected is strong and rigid even when formed of quite light stock. The side walls of the carton are effectively supported so that they are not likely to be collapsed inwardly upon the contents which may be quite delicate, such as certain bakery products or such as might be injured by squeezing. It will be understood that it is quite a general practice for prospective customers to pick up the package for closer inspection and they are not likely to be very careful in the handling of the package. However, as stated, the contents of the carton are well protected.

I have illustrated and described my invention in a practical commercial embodiment thereof.

I have not attempted to illustrate or describe certain embodiments or adaptations which might be desirable in the matter of size or the number of cells for the merchandising of various products, as it is believed that this disclosure will enable those skilled in the art to adapt or embody m invention as may be desired.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:
